Application of a Third Generation Wave Model for Coastal Zone Management: Preliminary Set-up of SWAN Simulations for the Italian Seas
The application, tuning and optimisation of a third generation SWAN wave model to the Italian Seas is here analysed in terms of statistical and deterministic properties. Specifically we focus on the capabilities of the model to reproduce experimental data from wave buoys with the main aim to quantify the confidence limits of the forecasts when used for operational purposes at sea.
The model was run to simulate a continuous 12 months period (November 2004 \u2013 October 2005), forced with wind fields derived from an 0.25 deg resolution ETA model over the entire Mediterranean Sea. The numerical results of significant wave height, peak period and mean wave direction are compared with the data available from 13 wave buoys of Rete Ondametrica Nazionale \u2013 RON (Italy), both in a statistical (Wave Scatter Diagrams) and deterministic (time domain) analysis

Da nova geração de poetas, Laura Accerboni (Genova, 1985) Ă© sem dĂșvida uma voz que jĂĄ vem chamando a atenção dos leitores de poesia. âKrisis - Tempos de Covid-19â Ă© um projeto do NĂșcleo de Estudos ContemporĂąneos de Literatura Italiana da UFSC. A proposta Ă© criar um espaço de reflexĂŁo, e tambĂ©m um arquivo, sobre a experiĂȘncia trĂĄgica da pandemia de Covid-19 que vem devastando a vida de todos nas mais diferentes latitudes. O sustento das famĂlias, o convĂvio social, o trabalho remoto, as caras conquistas em relação Ă liberdade de ir e vir sofreram grandes abalos no inĂcio de 2020. Como nos comportamos diante dessa situação de emergĂȘncia? Quais sĂŁo os limites de uma situação de urgĂȘncia? Como pensamos e nos relacionamos com o outro? Como pensar o pĂłs-pandemia? Todas essas questĂ”es sĂŁo abordadas pelos nossos convidados, escritores, poetas e artistas italianos, a quem agradecemos pela participação.Laura Accerboni - âKrisis - Tempos de Covid-19â Ăš un progetto del Nucleo di Studi Contemporanei di Letteratura Italiana (NECLIT), attivo a FlorianĂłpolis (Brasile) presso lâUniversitĂ Federale di Santa Catarina (UFSC). La proposta Ăš creare uno spazio di riflessione, nonchĂ© un archivio, sulla tragica esperienza del Covid-19 che sta devastando la vita di tutti alle piĂč diverse latitudini. Il sostenimento delle famiglie, la convivenza sociale, il cosiddetto smart working, le ambite conquiste rispetto alla libertĂ di circolazione, hanno subito grandi scossoni allâinizio di questo 2020. Come ci comportiamo di fronte a questa situazione emergenziale? Quali sono i limiti di una situazione di urgenza? Come pensiamo e ci rapportiamo con lâaltro? Come pensare la post-pandemia? Sono questi gli interrogativi trattati dai nostri invitati, scrittori, poeti e artisti italiani, che ringraziamo per la partecipazion
Ten-month observation of the bottom current regime across a sediment drift of the Pacific margin of the Antarctic Peninsula
We present two time series of bottom current and temperature collected 8 m above the seabed on either side of a large sediment drift located on the continental rise of the Pacific margin of the Antarctic Peninsula. The mean current speed is comparable (6.2 cm sâ1 and 6.1 cm sâ1 respectively), but the mean direction differs by about 121°. The direction of mean flow follows the bathymetric contour, and the maximum speed never exceeds 20 cm sâ1 (below the typical benthic storm threshold). The potential temperature is remarkably stable (0.11 ± 0.01°C and 0.13 ± 0.02°C at the two sites). The cross-covariance indicates a significant peak at 20.2 days lag, slightly longer than the travel time of 18.7 days calculated between the two stations following the isobaths (98.4 km) and thus providing evidence for the topographic control on bottom water flow. The observed bottom water flow is consistent with deposition of Holocene hemipelagic sediments of the âdrift maintenanceâ stage. Indicators for palaeoceanographic conditions during glacial periods of the âdrift maintenanceâ stage and the older âdrift growthâ stage are at present too scarce to understand fully how the past oceanographic conditions influenced the evolution of the drifts
